Re: Active Noise Reduction Headsets

We were given little black ANR boxes on the Sea harrier after they worked out how much hearing damage we were getting. The figures for the back seat of the T Bird were particularly shocking. The little black box took 3 x 12v batteries and I would change them every 2 flights because when they did fail it also sounded like the engine was surging! Once the batteries failed it was even noisier than the old system. Having said that, I would never like to fly the Sea Jet without ANR once I had flown with it.
The wire from the black box was a pain as it was easy to snag. The box would usually fit into the thigh pocket with the wire attaching to a spilt in the pig tail helmet. There was talk of ANR being incorporated into the seat of the GR7 to avoid black boxes - but then again there is a lot of talk!
